How To Make Sausage Stuffed Mushrooms
- Begin by preheating the oven to 375°F and spray a large baking pan with nonstick cooking spray. Set the baking pan aside.
- In a large skillet, add the Italian sausage and onion and cook over medium heat until it has all turned brown. This should take about 8 minutes.
- Add the diced mushroom stems, garlic, salt, oregano, parsley and pepper to the skillet. Stir and cook for about 5 minutes or until the mushrooms have reduced significantly.
- Stir in the cream cheese and heat until it is fully melted. Once melted, add ¾ of the mozzarella and ¾ of the parmesan cheese to the skillet and stir and cook until fully combined and melted..
- Remove the skillet from heat and let the mixture cool down for about 5 minutes before stirring in the egg.
- Once the mixture has slightly cooled, place the mushrooms in the previously set aside baking pan and fill each one with about a tablespoon of filling.
- Sprinkle on the remaining mozzarella and parmesan cheese on top and bake for 20 to 25 minutes or until the top of the cheese starts to bubble and turn a dark brown color.
- Serve the stuffed mushrooms with a sprinkle freshly chopped parsley as a garnish if desired. Enjoy!
Tips and Variations
- Sprinkle in red pepper flakes for some tasty spice.
- Add breadcrumbs on top for a really delightful crunch.
- If you’re having trouble with your mushrooms staying upright while baking, use a mini muffin pan to keep them contained!
- Chives, rosemary, basil, all would be great additions to the stuffing mixture.
